As a core power machine in the agricultural and engineering fields, the tractor's core advantage lies not only in its own traction capacity but also in realizing "one machine with multiple uses" by replacing different attachments. This breaks the limitations of single operation and adapts to diverse production scenarios. From traditional farming to modern infrastructure construction, from farmland maintenance to site cleaning, the combination of various attachments makes tractors a cross-field multifunctional operation equipment, greatly improving equipment utilization and production efficiency. Combined with practical industry applications, this article will detail the core functions and applicable scenarios of tractors after attachment replacement.

I. Agricultural Production Attachments: Lay a Solid Foundation for the Whole Process of Agricultural Production

Agricultural production is the core application scenario of tractors, and supporting attachments cover the whole process of plowing, sowing, field management and harvesting. They solve the pain points of low efficiency and high cost of traditional manual labor, and are a key support for large-scale modern agricultural planting.

(1) Plowing and Land Preparation Attachments: Improve Soil Conditions and Lay a Foundation for Planting

These attachments are mainly used for the preliminary arrangement of farmland. According to different soil conditions and planting needs, they realize soil loosening, crushing and leveling, creating a good environment for seed germination and crop growth.

1. Rotary Tiller: As the most commonly used attachment for farmland land preparation, the rotary tiller drives the rotary tiller blades to rotate through the tractor's power take-off (PTO). It cuts and stirs the soil, and at the same time mixes organic matter such as straw and weeds on the surface into the soil to realize straw returning to the field and improve soil fertility. The rotary tiller has strong adaptability, and its operation depth and speed can be adjusted according to soil hardness and plot size. It is suitable for conventional land preparation of paddy fields and dry fields, especially for the pre-planting preparation of vegetables and food crops, with an operation efficiency more than 20 times that of manual plowing.

2. Subsoiler: Aiming at the problem of soil compaction caused by long-term rotary tillage, the subsoiler can penetrate 30-50 cm into the soil, break the hard plow pan without disturbing the original soil structure, enhance soil air permeability and water storage capacity, and reduce soil erosion. In arid and semi-arid areas, subsoiling can effectively improve soil water retention capacity, help crops resist drought and increase production, and is widely used in large-scale planting bases of field crops such as corn and wheat.

3. Disc Harrow: Divided into light harrow, medium harrow and heavy harrow, it is mainly used for soil crushing and leveling after rotary tillage, as well as straw crushing and returning to the field after harvesting. The light harrow is suitable for surface soil crushing and breaking compaction; the heavy harrow can handle heavy soil, crush large soil clods and straw, ensure the surface is flat, and facilitate subsequent sowing operations. In southern paddy fields, the disc harrow can also be used for paddy field leveling and mud mixing, adapting to the land preparation needs of rice planting.
